const (
	Wei   = 1
	GWei  = 1e9
	Ether = 1e18
)

These are the multipliers for ether denominations. Example: To get the wei value of an amount in 'gwei', use 

new(big.Int).Mul(value, big.NewInt(params.GWei))

Local constants to replace upgrade package constants

View Source 
var Version = func() string {
	return fmt.Sprintf("%d.%d.%d", VersionMajor, VersionMinor, VersionPatch)
}()

Version holds the textual version string.

View Source 
var VersionWithMeta = func() string {
	v := Version
	if VersionMeta != "" {
		v += "-" + VersionMeta
	}
	return v
}()

VersionWithMeta holds the textual version string including the metadata.

Functions

func GetExtra 

func GetExtra(c *ChainConfig) *extras.ChainConfig

func SetEthUpgrades 

func SetEthUpgrades(c *ChainConfig) error

SetEthUpgrades enables Ethereum network upgrades using the same time as the Lux network upgrade that enables them.

TODO: Prior to Cancun, Lux upgrades are referenced inline in the code in place of their Ethereum counterparts. The original Ethereum names should be restored for maintainability.

func SetNetworkUpgradeDefaults 

func SetNetworkUpgradeDefaults(c *ChainConfig)

func VersionWithCommit 

func VersionWithCommit(gitCommit, gitDate string) string

Types

type ChainConfig 

type ChainConfig = ethparams.ChainConfig

ChainConfig is the core config which determines the blockchain settings.

ChainConfig is stored in the database on a per block basis. This means that any network, identified by its genesis block, can have its own set of configuration options.

func Copy 

func Copy(c *ChainConfig) ChainConfig

func WithExtra 

func WithExtra(c *ChainConfig, extra *extras.ChainConfig) *ChainConfig

WithExtra sets the extra payload on `c` and returns the modified argument.

type ChainConfigWithUpgradesJSON 

type ChainConfigWithUpgradesJSON struct {
	ChainConfig
	UpgradeConfig extras.UpgradeConfig `json:"upgrades,omitempty"`
}

func ToWithUpgradesJSON added in v0.8.4 

func ToWithUpgradesJSON(c *ChainConfig) *ChainConfigWithUpgradesJSON

ToWithUpgradesJSON converts the ChainConfig to ChainConfigWithUpgradesJSON with upgrades explicitly displayed. ChainConfig does not include upgrades in its JSON output. This is a workaround for showing upgrades in the JSON output.

func (ChainConfigWithUpgradesJSON) MarshalJSON 

func (cu ChainConfigWithUpgradesJSON) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler. This is a workaround for the fact that the embedded ChainConfig struct has a MarshalJSON method, which prevents the default JSON marshalling from working for UpgradeConfig. TODO: consider removing this method by allowing external tag for the embedded ChainConfig struct.

func (*ChainConfigWithUpgradesJSON) UnmarshalJSON 

func (cu *ChainConfigWithUpgradesJSON) UnmarshalJSON(input []byte) error

type Rules 

type Rules = ethparams.Rules

Rules wraps ChainConfig and is merely syntactic sugar or can be used for functions that do not have or require information about the block.

Rules is a one time interface meaning that it shouldn't be used in between transition phases.

type RulesExtra added in v0.8.4 

type RulesExtra struct {
	IsSubnetEVM bool
}

RulesExtra represents extra EVM rules - part of libevm integration

func GetRulesExtra added in v0.5.5 

func GetRulesExtra(rules Rules) RulesExtra

GetRulesExtra stub - was part of libevm integration

func (RulesExtra) IsPrecompileEnabled added in v0.8.4 

func (r RulesExtra) IsPrecompileEnabled(addr common.Address) bool

IsPrecompileEnabled checks if a precompile is enabled
